Table 53: Commands to Disable or Reset STP
Command Description
delete stpd <stpd_name> Removes an STPD. An STPD can only be removed if all
VLANs have been deleted from it. The default STPD, s0,
cannot be deleted.
disable ignore-bpdu vlan <name> Allows the switch to recognize STP BPDUs.
disable ignore-stp vlan <name> Allows a VLAN to use STP port information.
disable stpd [<stpd_name> | all] Disables the STP mechanism on a particular STPD, or for
all STPDs.
disable stpd ports <portlist> Disables STP on one or more ports. Disabling STP on
one or more ports puts those ports in forwarding state; all
BPDUs received on those ports will be disregarded.

STPDs.
